标题: 修改了init.rc 编译后刷机后白屏，是怎么回事？
x210ii  7寸电容屏

修改了 android.img.cpio 中的 init.rc:
红色为加入部分：

# gsensor
chmod 666 /dev/sensor
chmod 666 /dev/kxtf9_aot
chmod 666 /dev/s3c2410_serial0
chmod 666 /dev/s3c2410_serial1
chmod 666 /dev/s3c2410_serial2
chmod 666 /dev/s3c2410_serial3

android/kernel/arch/arm/mach-s5pv210/mach-smdkc110.c文件头定义：
#define AT070TN92    1
#define VGA_800X600    2
#define VGA_1024X768 3
#define DISP_MODE    AT070TN92
//#define DISP_MODE    VGA_800X600
//#define DISP_MODE    VGA_1024X768

用命令  ./mk -ki  编译得到 zImage

用dnw + fastboot 刷入：
x210.img （因为编译麻烦此文件为光盘自带文件）

fastboot flash bootloader L:\andorid\uboot.bin
fastboot flash kernel l:\andorid\zImage
fastboot flash system E:\X210II_A\android2.3\image\inand\LCD070\x210.img （因为编译麻烦此文件为光盘自带文件）
fastboot -w

OM5 设置为OFF 后重启开发板，白屏。

请高手帮忙啊，折腾很久了。。。

内核里面在menuconfig里面，有一个framebuffer，里面有LCD选型的，选择AT070TN92

为何我的板子里内核里面没有 menuconfig

痛苦的问题啊

请教一下，我的板子出现如下打印：

然后内核会不断打印如下信息：
set up rclk:512*44100 substream:0
DmaAddr=@c0000000 Total=32768bytes PrdSz=8192 #Prds=4 dma_area=0xe0900000

Entered smdkc100_hw_params 135

其中“smdkc100_hw_params 135”指的是声卡部分，难道我的这个问题和声卡驱动异常有关？
再次谢过！！！
